近十几年来,新兴的粉碎工程学得到了迅速的发展。这门科学主要是研究粉碎(破碎与磨矿)的理论、工艺、设备和应用。粉碎工程学的重要性在于自然界的矿物原料都必须经过粉碎后才能应用。据统计,全世界每年经过粉碎的物料达40亿吨。碎磨这些物料的能耗占世界总能耗的3～4％, In recent decades, the emerging crushing engineering has been rapid development. This science is mainly to study the theory of crushing (grinding and grinding) theory, technology, equipment and applications. The importance of crushing engineering is that natural mineral materials must be crushed before they can be applied. According to statistics, the annual crushed material in the world reaches 4 billion tons. The energy consumption of grinding these materials accounts for 3 ~ 4% of the total energy consumption in the world,
